San Antonio Spurs 61, Celtics 53

Video Highlights

LAS VEGAS - Esthetically, Summer League games aren't what you'd call works of art. Monday's loss to the Spurs was one of the uglier games you'll see. Despite leading for three quarters, the Celtics fell apart in the fourth and were outscored 25-11 in the fourth quarter in a 61-53 defeat to the San Antonio Spurs Monday.

Despite leading for three quarters, it all appeared to fall apart in the fourth. What happened?

"The same thing that was going on the whole game," Hill said. "They weren't moving the ball, they weren't executing. The bigs, when they caught the ball, the ball stopped. When they tried to post up, if they didn't get the ball, they pouted. But you can't score if you keep turning the ball over."

Twenty-nine turnovers in a 40-minute game borders on the ridiculous, and Hill was frustrated by the overall lack off ball-movement that stymied the Celtics offense. He said that guys played selfish, and having just five total assists would certainly back up that assertion.

Meanwhile, Hill blamed the turnover epidemic on guys not playing within their roles.

"I thought Doc explained that really well to them. The first thing that you have to do is understand your role. Work on your role during the summer," Hill said. "Anybody can score in summer league, but you don't play like that. You've got to play and understand what Doc is looking for. You're trying to get ready to play for Doc. If you don't understand that then there's a problem."

A few other problems: The Celtics shot just 33% from the field and went 1-9 from the arc. Gerald Green struggled (3-10) from the field, while Rajon Rondo committed seven turnovers himself.

The Celtics are off on Tuesday and will meet Yi Jianlian and the Chinese National Team on Wednesday night.
